摘要
本研究通过茶园定点试验和现场试验，对SPS-GPS (Standard Positioning Service GPS)接收机作为定位装置的精度和可用性进行了评价。SPS-GPS定点连续观测12小时，定位精度约5.33 m (2 d RMS)。利用GPS，一名操作人员13分钟即可轻松完成1349m2(±3%)茶田面积的绘图和计算。因此，GPS具有足够的精度，是一种简单的收集地理信息的设备。
Accuracy of SPS-GPS and Application to Tea Field Management
In this study, accuracy and availability of SPS-GPS (Standard Positioning Service GPS) receiver as a positioning device was evaluated by a fixed-point and site test in a tea field. The SPS-GPS has a positioning precision of about 5.33 m (2 d RMS) with continuous observation for 12 hours at fixed-point. By using GPS, plotting and computing 1349m2(±3%)area of tea field can be done easily in 13 minutes by a single operator. Therefore, GPS has sufficient accuracy, and is a simple device to collect geographical information.
